What is Cystic Fibrosis (CF)?

CF is an inherited chronic disease that affects the lungs and digestive system. A defective gene causes the body to produce unusually thick, sticky mucous that clogs the lungs and leads to life-threatening lung infections, obstructs the pancreas and stops natural enzymes from helping the body break down and absorb food. The predicted median age of survival for a person with CF is now more than 37 years old.
